• Ffmpeg 3.4 "Cantor" now support for svg rasterization

  12 janvier 2018, par Olivier Etienne

  Ffmpeg now support librsvg support for svg rasterization (source : https://www.ffmpeg.org/)

  I have tried the following command :
  ffmpeg -i test.svg test.png

  but I get the following error :
  Decoder (codec svg) not found for input stream #0:0

  I have search the doc but there is no examples given
  Can someone tell me how to a command line using ffmpeg to generate a png from an svg file ?

  Any help would be greatly appreciated.

  Thanks.

• Running frei0r filters with ffmpeg - "Could not find module 'pixeliz0r'."

  4 avril 2016, par ksloan

  I installed frei0r using homebrew

  MacK:tmp kevin$ brew list frei0r
  
  /usr/local/Cellar/frei0r/1.4/include/frei0r.h
  
  /usr/local/Cellar/frei0r/1.4/lib/frei0r-1/ (119 files)
  
  /usr/local/Cellar/frei0r/1.4/lib/pkgconfig/frei0r.pc
  
  /usr/local/Cellar/frei0r/1.4/share/doc/ (4 files)

  Then I installed ffmpeg with the --with-frei0r flag, and everything compiled fine

  brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-libass --with-libquvi --with-libvorbis --with-libvpx --with-opus --with-x265 --with-frei0r

  I tried telling ffmpeg where my frie0r filters were installed with

  export FREI0R_PATH=/usr/local/Cellar/frei0r/1.4/lib/frei0r-1/

  I even created symlinks from the default locations ffmpeg checks...

  MacK:tmp kevin$ ls -l  /usr/local/lib/frei0r-1
  
  lrwxr-xr-x  1 kevin  admin  33  4 Apr 04:43 /usr/local/lib/frei0r-1 -> ../Cellar/frei0r/1.4/lib/frei0r-1

  But I’m still seeing this error :

  [Parsed_frei0r_0 @ 0x7f8938f003c0] Could not find module 'perspective'.
  
  [AVFilterGraph @ 0x7f8938f00160] Error initializing filter 'frei0r' with args 'perspective'
  
  Error initializing complex filters.
  
  Invalid argument

  Full output :
